In 1960, explored the possibility of hyperactivity as a biologically based neurological disorder explored by Stella Chess. Stella Chess believed the symptoms of hyperactivity to be physiologically oriented, rather than being caused by brain damage or poor parenting. Many school age children began to be diagnosed as having minimal brain dysfunction (Hunter, 1995).

Many gave Virginia Douglas credit for influencing the name change of this disorder.
